First Claim
1. A vehicle comprisingone of a hybrid vehicle and an electric vehicle;
- an energy storage component; and
a computer programmed to;
identify if a vehicle position is associated with link data in a database of historical power usage data, the link data comprising measured historical power usage data for a link of vehicle travel; and
if the vehicle position is associated with the link data;
obtain the link data of the link from the database, the link data absent terrain information from the database;
determine an expected vehicle power usage of the vehicle based on the obtained link data; and
optimize usage of the energy storage component based on the expected vehicle power usage and based on efficiency and life cycle costs of the energy storage component of the vehicle.

Abstract
A system for optimizing energy storage component usage in a vehicle comprising one of a hybrid vehicle and an electric vehicle, the vehicle comprising a computer programmed to identify if a vehicle position is associated with link data in a database of historical power usage data, the link data comprising measured historical power usage data for a link of vehicle travel. If the vehicle position is associated with the link data, the computer is programmed to obtain the link data of the link from the database, the link data absent terrain information from the database. The computer is also programmed to determine an expected vehicle power usage of the vehicle based on the obtained link data and optimize the energy storage component usage based on the expected vehicle power usage and based on efficiency and life cycle costs of an energy storage component of the vehicle if the vehicle position is associated with the link data.

13. A method comprising:
-
determining whether a vehicle position of one of a hybrid vehicle and an electric vehicle is associated with a first link dataset in a database of historical power usage and velocity data, the first link dataset comprising measured power usage and velocity data related to a first link of vehicle travel; and if the vehicle position is associated with the first link dataset; querying the database to obtain historical power usage and velocity data from the first link dataset, the queried data free of elevation data for the first link; calculating an expected power usage for the vehicle based on the queried data; and optimizing an energy storage component usage for an energy storage component of the vehicle based on the expected power usage and based at least on efficiency and life cycle costs of the energy storage component of the vehicle such that operation of the energy storage component based on the optimized expected power usage achieves a desired usage of the energy storage component. - View Dependent Claims (14, 15, 16, 17, 18)
